Section Includes: <br />1. Glazed, four-sided structural-sealant-glazed curtain-wall assemblies. <br />1.2 PREINSTALLATION MEETINGS <br />A. Preinstallation Conference: Conduct conference at Project site. <br />1.3 PRECONSTRUCTION TESTING <br />A. Preconstruction Testing Service: Provide structural-sealant-glazed curtain walls <br />that comply with test-performance requirements indicated, as evidenced by reports <br />based on Project-specific preconstruction testing or tests performed on <br />manufacturer's standard assemblies by a qualified testing agency. <br />1. Engage a qualified testing agency to perform preconstruction testing on <br />laboratory mockups. <br />2. Build laboratory mockups at testing agency facility using personnel, materials, <br />profiles, finishes and methods of construction that will be used at Project site. <br />3. Notify Architect seven days in advance of the dates and times when <br />laboratory mockups will be constructed. <br />4. No pre-testing of final test assembly shall be allowed without Architect and <br />Owner’s consent. <br />5. The test assembly shall be erected under supervision of the installation <br />personnel that will supervise installation at the project site. <br />6. The mock-up shall incorporate adequate viewing holes at lower corner of <br />backpan to review drainage of ventilated shadowbox cavity. <br />7. Install thermal insulation for thermal testing only after completion static and <br />dynamic water testing. <br />8. Preconstruction Testing Program: Perform tests specified in "Performance <br />Requirements" Article on laboratory mockups in the following order: <br />a. Structural-performance preloading at 50 percent of specified wind-load <br />design pressure when tested according to ASTM E 330. <br />b. Air infiltration when tested according to ASTM E 283. <br />c. Water penetration under static pressure when test ed according to <br />ASTM E 331. <br />d. Water penetration under dynamic pressure when tested according to <br />AAMA 501.1. <br />e. Structural performance at design load when tested according to <br />ASTM E 330. <br />f. Repeat air filtration when tested according to ASTM E 283.
